Make sure the devices lte bands match that of your carriers lte bands. Dont look at 2g and 3g bands. Only lte bands. Second id say make sure your apn settings are correct.
And last is make sure in mobile networks you have global or gsm cdma and lte selected

A lot of times this could be due to specific hardware not picking up propper lte bands or those bands not being enabled. Which u can google on enabling hidden lte bands. I didnt notice what model u had from the seller. I noticed u said manipulations of unlocking bl so where u sucsessful? Then its a h815 i believe which would be the global model. Which then could be software relTed or a settings issue.

I had not specified that it is a h815 international version but planned for a planned commercialization in Singapore. According to my operator the antenna 4g near my home uses only the band 800 which is normally compatible with ... I also have a lg g4 that works perfectly with my chip. All APN settings are correct .. Is there a way to force to use this tape?
I tried manipulation to unlock the bootloader with the official version of LG but it is an Asian phone .. I thought of a software problem so I tried with lg bridge that does not pick up my phone. Is there any other way?

Help to unlock net a LG G7 LM-G710EM of Tigo El Salvador

Hello!, a couple of days ago I bought an LG G7 LM-G710EM, this has a Tigo operator Rom for Central America (I'm from El Salvador). I want to use the phone with a Movistar SIM. To do this, I bought a SIM unlock code from lgsimunlock.com, but it did not work. I want to know if to flash stock Movistar ROM or a European ROM, this would unlock the phone. I have seen on the site lg-firmwares.com the variants of European Roms, but I am not sure that they can work for me. The software version of my LG is V10b-TGO-XXX. I'm not sure if the ROM of Movistar G710EM10b_00_MOV_COM_OP_0824.kdz can unlock my phone, the versions on lg-firmwares.com are only the TFH for Chile and the TFP for Peru, there is no for Central America.
Thanks in advance!

Lte band 20

First, sorry for my english. I bought a Chinese version of MI 9 SE in China. So the device is without LTE band 20. Is there any possibility to unlock the LTE band 20? I use Xioami.eu Stable ROM.

"Usually all Xiaomi phones comes with two different hardware, one with chinese bands and one with global ones." Read here: https://forum.xda-developers.com/Mi-9/help/availability-lte-bands-t3902999.

Thx Vecino,
then it was probably a bad buy ...

Can someone please tell me which modem is installed in the respective version (China or Global)?

It has nothing todo with the modem. Its Hardware site removed/restricted. Alot of people tryd allready with other phones to open band 20, with no luck.
Try this if you think it should work...but i dont think so..
https://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774
Das ist Hardware mässig gesperrt/entfernt wurden. Da kann man nix machen. Bei Xiaomi falls LTE band 20 benötigt wird, immer die Global Version kaufen.

That would interest me too

Code:
13. click on line 06828 (lte_bc_config); click the Read button
I tried all the methods available, no luck. Our phones doesn't have that parameter at all. LTE bands are configured somewhere else. I am leaning the way that we need some kind of modified QCN file. I got original QCN backup before starting mess with fsg and modemst1 partitions. But I think QCN is not restoring the original state. If only I could have EFS partition backup (didn't know what it is then). If you know somebody willing to share his/her EFS, it would be starting point.

Can i flash any android 10 on G7 EAW HKG?

There's still no rumors about update to 10 Android for HKG 6/128 version. "Ay hate this sh1t"
So, could someone give a hint what ROM is it possible to flash on EAW 6/128? I mean w/o rooting, cracking boot and all that. Or there's not such ways and I should sell it with Pie and jump to somthng more actual?

I've G7+EAW 6/128 HK version based on the IMEI. I upgrade to Android 10 EAW Indian version using LG UP. Download KDZ file from lgfirmwares or join Telegram group for G7 ThinQ Development, somebody have GDrive link for the kdz file.

I've 2 SIM devices, but only use 1 SIM (another slot I use for memory card) so I don't test other SIM work or not. But in setting menu still show SIM Card 2 (grey out because no SIM inserted). I'm Indonesian, and so far LTE work normally with my telco operator. I didn't lose my IMEI and SN, both still same as previous. NFC work but don't now about GPay because it's not available in Indonesia.
Only one annoying thing, when I restart the phone, always come out notification: "current version is not available for user. Can't find matched carrier. NT-Code: FFFFFF:54". However it's seems only notification, the phone working properly.

Question OnepLus 9 Pro Le2127 Converted to Le2125

For the last few updates OB2 - F.18 there has been no dual sim bug. Now OnePlus pushed out F.20 the dual sim bug is back. Do we have a fix ? Or just stay on F.18 ?

Hi, did you managed to make the dual sim work on the F.18 update ?

No it would not work I tried EU and NA on F.18 and F.20 no joy !

I have not, my Le2127 converted to Le2125 is running flawless on F.18 so until I get bored with it I'm gonna leave it alone. But I do have 2 active sim cards I would be interested if anyone knows a way to do it and be on or upgrade to OOS 13

ok, thanks for the answers and hope to find a solution one day

Son birkaç güncelleme için OB2 - F.18 çift sim hatası olmadı. Şimdi OnePlus, F.20'yi çift sim hatası geri itti. Bir düzeltmemiz var mı? Ya da sadece F.18'de kalmak mı?
